In the NE I think Rev-ups were the norm at least in the mid 80's. Once the noise limits came into play people started stretching the pipe length and going to higher pitched props. There were a bunch of nylon MK props some with progressive pitch with labels like 1+ and 2+. I remember a gray stiff plastic prop by Yoshioka model factory, GFA carbon props, Bolly, and as I mentioned DW which I ended up using. I think the rev-ups were the most popular during the screaming engine period as they were light, thin and I suspect under pitched. If a rev-up 11-7 spun at 15,000 and a top flite 11-7 at 14,500, most would go with the rev-up.
